← ScienceWhich effect does extreme spacetime curvature near a Kerr black hole event horizon produce on infalling light?
A)Intense blueshift and orbital distortion✓
B)Reduced velocity and spectral redshift
C)Complete transmission without alteration
D)Polarization shift and amplitude damping
💡 Explanation
Spacetime curvature intensifies near black holes causing extreme gravitational effects; the **gravitational blueshift** mechanism acts on incoming photons, heavily increasing their frequency, rather than decreasing it, because the curvature is steep and light races to the singularity; therefore light is blue/orbitally distorted.
